Title: fs: Remove default lowWaterMark option from ReadStream() to fix regression

The water mark causes a regression, compared to 0.8, when reading from certain non-files, and can cause a thrown error if a small value of highWaterMark is specified.

I have a included a new test case, which fails without the patch, but works using node 0.8.x.
